The K&N 57-2549 Air Intake fits some Ford F150 Harley Davidson, and Ford F150 Lightning models. See vehicle applications link for details.
The K&N 57-2549 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Ford F150 models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your F150’s engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 57-2549 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The tube accommodates the factory mass air sensor, idle air and crank case vent lines. The oversized cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using the existing factory mounting points. The tools needed are a screw driver, ratchet set and several wrench. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

K&N 57-2549 Air Intake Product Reviews

Saturday, January 28, 2017 - Part 57-2549
Excellent installation instructions (lots of detailed photographs). Replaced an Air Raid intake on a 2002 Harley Davidson Supercharged F150, K&N unit had the all important CARB exemption sticker that is vital in California. Works and sounds great.

K&N filters always give better performance. It made my lightning boost more and definitely made the supercharger louder. Thanks for the great filter and good customer service.
